Philco 46-480 Electronic Restoration
#3

Thank you, Richard! The biggest effort is to create all of the symbols which don’t exist in much of the newer circuit software. It was a labor of love, but I’m happy to share what I find. I plan to get this schematic updated with all of my findings after going through the chassis. I’m always afraid to start disassembly until I am absolutely confident that I have the documentation to put it back together correctly.
